RF Waveform for Long Distance

[user3344]

Posting this in hardware because it seems like the most appropriate...

We are conducting some localization experiments where we will be capturing advertising packets of an NRF58240 that is in long distance mode, using a USRP.  In order to do so, we need to figure out the what the waveform of the packet looks like on the wire, and the data coming through.  Long distance mode has additional bits for FEC correct?  Are their tools out there that can give me what the actual waveform will look like (its DPSK?).  In order to make this simpler, we know what the advertising packet data is.  So I guess my question is, any ideas of where to begin?

Thanks

Surely, this is defined by the Bluetooth Specifications ?

Its in the spec but reconstructing the on air pattern from scratch is going to be cumbersome / error prone.  I am hoping there is a tool around where I can say - this is the ADV packet from my nrf52840, and this is the on air waveform.
